Dumbbell Flyes

Dumbbell Flyes develops the mass and strength of the pectoral muscles. Dumbbell flyes are an isolation exercise. This means only one muscle is working: the chest (unlike bench press where the shoulder and triceps are also assisting you). Dumbbell flyes give you a better stretch than any other exercise and this stretch can actually grow the muscle itself even quicker.
